BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention is related to an anti-hijack system and ananti-hijack method in a mode of forestalling the enemy, and especiallyto such a system and such a method applicable to a vehicle such as anairplane or the like to separate the pilot from the passengers.

[0003] 2. Description of the Prior Art

[0004] The reason why hijacks have been frequently made is thathijackers got the idea that people worry about the safety of passengersand crews and have to compromise with them. No matter the event is largeor small, no matter the time spent for the event is long or short, thefinal result must make the society pay a large cost. Especially in thecase of the 911-event at the World Trade center in the U.S.A., thedisaster was terribly sad, it influenced all countries around the world.We can see the scoundrels have deeply been planted with the valueconcepts that are worth death, and negotiation will no more be a goodway to deal with a hijack; this largely threaten the safety of flightand development of international economy.

[0005] As a result, the air traffic prosperously developing day by dayand being convenient for all the people originally makes people afraidof suddenly; and we can feel the moods of those who cannot help taking aflight. These render those related businesses (such as the airplanemanufacturing art, airline companies, travel agents etc.), passengers,people relating to those buildings subjected to being targets and thepeople nearby them horrified and thus hard to get along all the time.However nowadays, all nations do not have a good way to deal withhijacks except blaming and condemning, and can only hope to make a moreperfect examination before boarding a plane by searching and not toneglect even a knife. In facing to such cunning hijackersnotwithstanding, the hijackers can still do something even when theyboard unarmed. It can be expected that, ground safety examinationsystems and methods from now on will be not adequate for the scoundrelswho mean to crime, such crimes are out of the capability of prevention.

[0006] The inventor of the present invention analyzed the past hijacks,and thought that dealings of the hijacks formerly are hard studies incontest, negotiation and fighting against etc. after hijackers succeededwith controlling the entire state (kidnapping hostages), these areevidently deficient in lacking of the feature of forestalling the enemy.

[0007] In view that the conventional method stated above has the abovementioned defects, the inventor of the present invention studied anddeveloped an anti-hijack system and an anti-hijack method in a mode offorestalling the enemy, thereby during hijacking, passengers who canonly be hostages at the mercy of hijackers can have the advantage ofhaving many watching persons who are most close to the hijackers,thereby can be the roles of watchers on the safety of the passengercabin. They can rapidly advise the pilots in the cockpit to take anaction at the earliest moment in order that the event of hijacking canbe solved before it gets worse, and this is the motive of the presentinvention.

SUMMARY OF THE INVENTION

[0008] The primary object of the present invention is to provide ananti-hijack system and an anti-hijack method in a mode of forestallingthe enemy to solve the event of hijacking before it gets worse.

[0009] The secondary object of the present invention is to provide ananti-hijack system and an anti-hijack method in a mode of forestallingthe enemy, whereby every passenger can give an alarm signal to advisethe pilots in the cockpit to take a suitable action at the earliestmoment.

[0010] In order to achieve the above stated objects, the presentinvention includes an alarm system including a plurality of alarmdevices, a displayer, a signal recorder, a magnetic spring lock and asecurity device. Wherein the alarm devices each includes a plurality ofswitches provided on every of the chairs in the passenger cabin(including other activity spaces such as the kitchen, water closets,baggage compartment . . . ); the signal lines of the switches areconnected to the displayer and the signal recorder provided in thecockpit; the magnetic spring lock is provided on the cabin door of thecockpit; the security device is a normal paralyzing gas controller, theoutlets of the paralyzing gas are distributed all over the cabin; andthe security device is controlled by the persons in the cockpit. Ifthere is a case of hijack, every passenger can singly or simultaneouslyactivate the alarm system, the signals emitted from the alarm systemwill be received by the signal recorder to have the chair numbersencoded, and then are sent to the displayer. The displayer will displaythe positions where passengers activate the alarm system, and the numberof persons and the areas giving the alarms can be known. When thepersons in the cockpit get the alarm signals, the crews in the cabin canimmediately be noticed to wear the oxygen masks and eyeguards forself-protection, then the persons in the cockpit can rapidly activatethe security device to spray the paralyzing gas out of the outlets.Thereby, in an extremely short time period, all the persons in thecabins will be paralyzed by absorbing the paralyzing gas except thosecrews wearing the oxygen masks and eyeguards. Now the security personnelcan arrest in the first place the hijackers having revealed their own,then revive the persons giving alarms and the rest persons, and ask thealarm makers to assist to recognize those hijackers not certainlyrecognized. In this way, the event of hijacking can be solved before itgets worse, and no unnecessary sacrifice is paid.

[0011] The present invention will be apparent in its technical contents,features and effects after reading the detailed description of thepreferred embodiment thereof in reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0020] The present invention is comprised mainly of an alarm systemincluding a plurality of alarm devices 4, a displayer 15, a signalrecorder 14, a magnetic spring lock 17 and a security device 23.Referring firstly to FIG. 1, an airplane can be divided into a frontsection which is a cockpit 49 and a rear section which is a passengercabin 1, the cockpit 49 and the passenger cabin 1 are both provided withchairs 2 for seating, a box of each alarm device 4 is mounted on one ofthe armrests 3 of each chair 2 in the passenger cabin 1, the box isprovided therein with a photosensitive switch 5 and a snap switch 6, andis provided respectively on the upper and the lower sides thereof with acannel 10 which has a spring 11 therein to allow a protective cover 7 tobe pushed therein to prevent the photosensitive switch 5 and the snapswitch 6 from accidental pressing. The protective cover 7 is furtherprovided with a direction indicating mark 8 and a concaved surficialarea 9 for pressing by a finger (referring simultaneously to FIGS. 1aand 1 b). The signals from the photosensitive switch 5 and the snapswitch 6 are transmitted to the signal recorder 14 in the cockpit 49;the signal recorder 14 is connected with the displayer 15 (as shown inFIG. 1c) and the magnetic spring lock 17 which is provided in the cabindoor of the cockpit 49.

[0021] Referring to FIG. 2, generally, an airplane used presently hasits passenger cabin 1 and cockpit 49 arranged to use a common air supply18 and a common delivery pipe 19; please also refer to FIG. 3, when inusing the present invention, the delivery pipe 19 is provided on theoutlet thereof with a switch 26, the delivery pipe 19 is furtherprovided on the top thereof with a cockpit manifold 28 to led air intothe cockpit 49. And the cockpit manifold 28 is provided on the front endand the rear end thereof respectively with a passenger-cabin manifold 34and a ready-service room manifold 29. The passenger-cabin manifold 34 isprovided on the upper end thereof with a manifold switch 35 of which acontrol push-button 33 is provided in the cockpit 49. The ready-serviceroom 31 is provided therein with back-carrying type oxygen bottles 32.

[0022] The security device 23 is a container with a space, the containercan be loaded therein with paralyzing gas or tear gas, and is providedtherein with a pressurizer 25. The outlet of the container is providedwith a pipe, an outlet 27 of the pipe is communicated with the passengercabin 1; the pipe and the container have therebetween a switch 24 ofwhich a control push-button 22 is provided in the cockpit 49, thecockpit 49 is further provided with an alarm push-button 21 to informall the personnel in the cockpit 49.

[0023] Referring to FIG. 3a, each chair 2 is provided therein with achair-back manifold 37 of which the bottom end is connected with ahidden pipe line network 36, The pipe line network 36 is in turnconnected with the passenger-cabin manifold 34, the upper end of thechair-back manifold 37 is connected with a hose 39 of which the otherend is provided therein with a valve leaf to prevent air accessing, thevalve leaf is forced to open by a connector 42 of an oxygen mask 41, andan eyeguard 46 is attached here, which eyeguard 46 is not lighttransmissible. As shown in FIGS. 3b and 3 c, the oxygen mask 41 and theeyeguard 46 are provided on the lateral sides thereof respectively withtying belts 47 of which the tailing ends are provided each with anadjustment button 48 for adjustment of the tightness of wearing.

[0024] With the above stated combination, during flight, if hijackerswant to or start to act, but they are limited in number, and are unableto control all the passengers at the beginning, now the passengers cantake advantage of their plurality and closeness to the hijackers, theycan individually or simultaneously push away the protective covers 7 onthe alarm devices 4 provided on one of their armrests 3; by virtue thatthe actions of pushing away the protective covers 7 are very slight, thepassengers can do this without showing any evident action, thus canavoid irritating the hijackers and avoid immediate avenging of thehijackers. The photosensitive switch 5 is activated by light in order toprevent the photosensitive switch 5 from being out of work; thephotosensitive switch 5 is provided beside it with the snap switch 6capable of being activated by displacement of the protective cover 7 totransmit signals to the signal recorder 14 and the displayer 15 of thecockpit 49 to make an alarm for the pilots, the signal recorder 14 alsodrives the magnetic spring lock 17 to lock the cabin door of the cockpit49 to prevent hijackers from intruding.

[0025] When the pilots obtain alarm signals on the displayer 15, theycan show the situation through the alarm push-button 21 to the personnelin the cockpit 49, the personnel can immediately wear eyeguards 46 andoxygen masks 41 for self-protection, and can individually obtain airsupplying by the oxygen masks 41 through the cockpit manifold 28 and theready-service room manifold 29. And the switch 24 as well as thepressurizer 25 of the security device 23 can be activated withoutnoticing in advance, the switch 26 of the delivery pipe 19 in the airsupply 18 can be shut down to allow paralyzing gas to enter thepassenger cabin 1 through the outlet 27. By the fact that the airplaneis a tightly sealed space, persons at any corner of the cabins will beforced to absorb or contact the paralyzing gas to be paralyzed. After aperiod of time, when it is sure that the paralyzing gas works, thesecurity personnel in the cockpit 49 can wear the back-carrying typeoxygen bottles 32 with the information of the chair numbers encoded inthe signal recorder 14 carried on their own persons to be ready toarrest the hijackers.

[0026] At this time, the pilots can activate the manifold switch 35 ofthe passenger-cabin manifold 34 by mans of the control push-button 33 inorder to deliver the air in the air supply 18 from the passenger-cabinmanifold 34 into the hidden pipe line network 36, then through thechair-back manifolds 37 and the hoses 39 to thereby form anotherindependent air supplying system. The paralyzing gas is separated fromair; the security personnel then put the oxygen masks 41 and theeyeguards 46 on the persons giving alarms and the weak old people andchildren to revive the persons giving alarms in order to recognize thehijackers. After arrestment, the security personnel sequentially helpthe rest passengers to put on the oxygen masks 41 and the eyeguards 46to revive them.

[0027] Even if some hijackers are not arrested, by virtue that theparalyzing gas includes tear gas; and the hijackers not arrested have towear the eyeguards 46 which are not light transmissible, their eyesights are obscured, thereby they can not find the objects with theireyes; besides, the hoses 39 are limited by length, users must use themat the chairs respectively, this can restrain the hijackers not arrestedfrom getting close to the objects; even if the hijackers have their owntransparent eyeguards, they inspire normally and can not get the objectsby stopping respiration; in addition to this, hostages they get areunable to open their eyes but inspire the paralyzing gas under thecondition that the hostages do not wear eyeguards 46 and oxygen masks41, hence the ability of activity of the hostages nearly is zero, theycan not do in pursuance of the instructions of the hijackers. All theseunbeneficial conditions to the hijackers are advantageous to thesecurity personnel in dealing with the event.

[0028] Therefore, by combination of the alarm devices 4 with thesecurity device 23, the persons in the cockpit 49 can get alarm signalsat the earliest moment; under the priority of consideration of thesafety of flight, it is no necessity of worrying about that passengerswill be treated in the same way as that to the hijackers, thereby thehijackers can be rapidly controlled by immediately activate the securitydevice 23, this can avoid resistance from the hijackers that may hurtthose innocents. Every one are possible to be considered as a suspecthijacker before arrestment, it is thereby necessary to let every onefaint; after the security personnel do the arrestment, they helppassengers to put on oxygen masks 41 to supply air individually torevive them, the passengers will not suffer the paralyzing gas for along time. The flight may have to wait for landing, the paralyzing gascan only be cleared off by further processing of the ground staffs, andby virtue that the hoses 39 are limited by length, passengers can beadvised to keep still without over operation and avoid to hinder dealingwith the event.

[0029] When the alarm devices 4 are activated, the controllers in thecockpit 49 will immediately activate the security device 23, this mayhave to influence the physical as well as psychological states of thepassengers and the schedule of the flight; thereby, the alarm devices 4shall be prevented from activating at ones will unless in emergency.People shall be educated in general time. When the passengers board,flight attendants shall explain again the rules of using, and emphasizeno unnecessary touch (on purpose or by accidence). Once the alarmdevices 4 are activated, it is deemed as an alarm; if it is a lie tomake this false alarm, criminal punishment shall be born and hugereparations shall be paid. The signal recorder 14 can tell whichpassengers at the recorded positions of chairs make the alarms, this canforbid those fond of making trick from trying touching, in this way,nearly each alarm can be a right alarm and credible.

[0030] The anti-hijack system and the anti-hijack method in a mode offorestalling the enemy of the present invention includes the followingadvantages:

[0031] 1. In case of a hijack event, all the passengers in the passengercabin are hostage, based on the spirit of mutual taking care theneighbors among all the interdependent passengers who are in the sameairplane, the passengers naturally voluntarily want to be watchers, bythe advantage of the plurality of the passengers over the hijackers whoare scattered around, the passengers can rapidly advise the pilots inthe cockpit to take an action at the earliest moment before thehijackers control the general situation.

[0032] 2. The alarm devices are activated with slight actions, this canavoid irritating the hijackers and avoid immediate avenging of thehijackers.

[0033] 3. At the same time the persons in the cockpit obtain the alarmsignals, the cabin door of the cockpit will be automatically locked toprevent intruding of the hijackers.

[0034] 4. The-hijackers can be subdued in advance before the hijackevent is formed; this can eliminate unnecessary damage, the range ofdamage can be reduced to the minimum degree.

[0035] 5. The hijack event is rapidly eliminated before it is formed;this can thereby save waste of huge social cost.

[0036] In conclusion, the present invention is an anti-hijack system andan anti-hijack method in a mode of forestalling the enemy; it caneffectively eliminate the influence on the safety of flight due toairplane hijack, and is surely a novel invention.
